New method could make it harder for hackers in the future
Researchers have devised a method of generating random numbers that could shake up computer encryption.
University of Texas computer science professor David Zuckerman and PhD student Eshan Chattopadhyay have found that a "high-quality" random number could be generated by combining two "low-quality" random sources.
Random number generation is used for a variety of applications including cryptography and scientific modelling.
Zuckerman is quoted in Threatpost saying: "We show that if you have two low-quality random sources – lower-quality sources are much easier to come by – two sources that are independent and have no correlations between them, you can combine them in a way to produce a high-quality random number."
Their paper has caught the attention of other academics worldwide who have described the research as "pulse-quickening" and "a breakthrough in theoretical computer science."
"This is a problem I've come back to over and over again for more than 20 years," said Zuckerman.
